T0 at whom it may concern.-

Be it known that 1, ANDREW ORTMAYER, a citizen of the United States,residing at Ohicago, Illinois, have'invented a new and usefulImprovement in the Method of Stitching or Sewing, of which the followingis a specification.

The cases where my improvement may be employed are too numerous topermit of my describing-each of them here. Therefore I shall use as anillustration the application thereof in the making of a horse-collar,without, however, intending by so doing to limit myself to suchapplication alone, inasmuch as I am aware that my improved method may beused wherever it is desired to fasten two or more pieces of suitablematerial together in a strong and durable manner.

In using horse-collars as hitherto made the rim is frequently torn offwhen any heavy strain is exerted thereon, as in backing, &c. Thisdifficulty can, of course, be avoided by making three or four rows ofstitches; but this method is expensive, and a stitch has been neededthat should not add to the expense of making, but would be sufficientlystrong for the purpose. This it is the object of my invention toprovide, and by the method of stitching hereinafter described I obtainwhat I shall call a double grip upon the rim and shoulder, thusfastening them together in such a way that the rim will not be torn offunder the strains to which it is subjected. Other advantages derivedfrom this method of stitching are that more room is provided for thehame and that the edges of the rim are held so closely down upon theshoulder that sweat, dust, &c., cannot work under them and rot theleather, nor can the rope catch upon-the edges and tear oif'the run.

In the drawings, Figure 1 represents avertical sectionthrough one sideof a horse-c01- lar; Fig. 2, an elevation of a portion of the rimthereof, showing the method of stitching employed; and Fig. 3, aperspective view of a portion of Fig. 2, showing the stitching in solidlines and the collar in dotted lines.

A represents the rim of the collar, B the shoulder, C the longitudinalstitches, and D the oblique stitches.

In making a horse-collar the two edges of the shoulder thereof arebrought close together and laid flat on one another and the two edges ofthe rim then lapped over them, as shown in the drawings. The rim andshoulder are then stitched together by means of a thong or cord, asfollows: Starting at the point E, Fig. 3, the thong is pressed throughthe four thicknesses of the rim andshoulder, then carried longitudinallyparallel to the roll of the rim a suitable distance, then through to theother side. It is next carried obliquely to the point D,then passedthrough the material of the shoulder only, lapping over the edges of therim, as shown by the vertical lines. It is then passed through all fourthicknesses in two longitudinal stitches. Then another oblique stitch ismade, (shown at F,) then two more longitudinal stitches, and so on tillthe sewing is completed.

It is to be particularly observed that while in making a longitudinalstitch the thong is carried through all four thicknesses, in the case ofthe inclined or oblique stitches the thong passes through fourthicknesses at one 7 end, but through only two at the other, these twobeing the thicknesses of the'shoulder in the caseI have shown as anillustration. By

this means the edges of therim are bound closely to the shoulder by thethong passing over them, so that when a rope is passed around the collarit cannot catch in the rim at any place.

hile I prefer that there should be two longitudinal stitches to eachoblique one, this piece within the edges of the other, in passing athread or thong first through all the thicknesses of fabric to bejoined, then carrying it along substantially parallel to the edges ofthe fabrics and passing it again through all the thicknesses, thencarrying it obliquely to the edges of the outer piece, then through thethicknesses of the inner piece, then back and through all thethicknesses, as before, and so on, alternately, whereby the fabrics arefirmly bound together, substantially as described.

2. The method of joining the rim of a horsecollar to the shoulderthereof, which consists in placing the edges of the shoulder within theedges of the rim, then passing a thread or thong through all thethicknesses of riln ANDREW ORTMAYER.
